Save Our Spuds: Scientists find shield for potato blight
Scientists on Monday said they have found a gene to help protect potatoes from a blight that unleashed a devastating famine in Ireland in the 19th century.
Honey bees use multiple genetic pathways to fight infections
Honey bees use different sets of genes, regulated by two distinct mechanisms, to fight off viruses, bacteria and gut parasites, according to researchers at Penn State and the Georgia Institute of Technology.
Researchers master gene editing technique in mosquito that transmits deadly diseases
Traditionally, to understand how a gene functions, a scientist would breed an organism that lacks that gene - "knocking it out" - then ask how the organism has changed. Are its senses affected? Its behavior? ...
Experiment reveals diet, immunity and gene links in fruit fly
A scientific finding in fruit flies on the interplay of genes, nutrition and immunity provides insights that may one day inform personalized medicine.
How genes are permanently silenced by small RNAs
Marc Bühler and his team at the Friedrich Miescher Institute for Biomedical Research (FMI) have elucidated the mechanism underlying small RNA-mediated gene silencing, thus solving a mystery which has been ...
New research discovers 4-stranded DNA-binding protein conserved in plants and animals
When it comes to plants and animals, sometimes the two are more alike than you'd think.
Refined CRISPR/Cas genome editing accelerates generation of transgenic mice
Although the genome editing system known as CRISPR/Cas has revolutionized genetic research in cell lines, its overall efficiency has been relatively poor when used to generate genetically altered animals ...
Evolutionary novelties in vision
A new study from SciLifeLab at Uppsala University published in PLOS ONE shows that genes crucial for vision were multiplied in the early stages of vertebrate evolution and acquired distinct functions leading to the sophis ...
Antimicrobial CRISPR-Cas systems may be better weapons against bacteria than antibiotics
Antibiotics are compounds that can kill bacteria. Many antibiotics are produced naturally by bacteria themselves as they compete for food or living space with other bacterial species. Over time, bacteria ...
Researchers greatly increase precision of new genome editing tool
CRISPR-Cas9 is a powerful new tool for editing the genome. For researchers around the world, the CRISPR-Cas9 technique is an exciting innovation because it is faster and cheaper than previous methods. Now, using a molecular ...
